Sensitive and selective n-butanol gas detection based on ZnO nanocrystalline synthesized by a low-temperature solvothermal method

The ZnO nanocrystalline based sensor exhibits the high selectivity to n-butanol and good response recovery characteristics, linear response, short-term repeatability, as well as the long-term stability at operating temperature of 340 °C, which makes it to be highly promising candidate for practical detectors for n-butanol gas.357
